Shutting off/flashing dash lights in reverse.

So since the other night while driving home I go around a turn hit a rather large bump and bam, all my lights shut of, headlights, instrument cluster, radio, subs, and the car sputtered then the lights came back on and car coughed and started running smooth again. Had 1/4 tank of gas and was scanning it and nothing was out of normal operating range.

Next day go to back out of driveway, put it in reverse and lights go haywire(all the above mentioned lights) and car shuts off.

Now random bumps in the road set of the lights flashing and resets the radio and abs/brake light stay on.

Im thinking its a ground wire loose possibly? Thoughts?

Check the obvious stuff first:

Battery cables - battery secure?
Hot wire to starter - Ive seen this rub on the rad support and ground out when hitting bumps.

I know it sounds stupid but it could be your ignition switch.
 
dazedandconfused,

I agree with the "rico" too. If that doesn't fix the issue, consult with a certified technician for additional assistance.

Please keep us posted.

Pulled both terminals, retightened, and works like new, guess something that simple is a good starting point. I was already trying to figure out body grounds etc lol. Thanks Rico and Mr boosty!
